Metapocyrtuskitangladensis sp. n. a new Pachyrhynchuscumingii GR Waterhouse 1841 mimic from Mindanao Island Philippines

摘要

A description of a new species from the genus Metapocyrtus Heller, 1912 (Coleoptera: Curculionidae: Pachyrhynchini) from Mt Kitanglad Range Natural Park, an ASEAN Heritage Site in northern Mindanao is presented and illustrated. The recent discovery is also the first mimic record of Pachyrhynchuscumingii GR Waterhouse, 1841 which are both found in the same locality. A Coptorhynchus sp. showing similar elytral patterns was also documented to be part of the mimicry complex. The new species differs from the other two species in having a distinct transverse groove between forehead and rostrum and the antennal scape reaching beyond the hind margin of the eye.
